Sekisui Chemical Co., Ltd. manages a company patent portfolio in the Chemistry & Materials technology area, currently featuring 67 pending office actions. These actions are distributed among 59 distinct examiners, which indicates that while many examiners handle a single matter, some are responsible for multiple cases. The prosecution is spread across 34 distinct art units, reflecting an exceptionally high degree of technical diversity within the company's chemical and material science filings.
VO, HAI is identified as the busiest examiner for this portfolio, currently managing 3 busiest examiner pending office actions. These 3 actions represent a small portion of the 67 total pending office actions, highlighting that the workload is broadly distributed across the 59 distinct examiners. The influence of this busiest examiner is limited given the overall size and variety of the portfolio.
Practitioners should be prepared for a highly decentralized prosecution environment, as the 67 pending office actions are spread across 34 distinct art units. This distribution suggests that the company's filings span many different technical classifications at the patent office. With 59 distinct examiners involved, there is very little opportunity to leverage examiner-specific insights across multiple applications, requiring a unique approach for the vast majority of the 67 pending office actions.
Based on the USPTO statutory response window for each pending office action. 22 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
Every pending office action with a known statutory deadline, placed on a days-until-due axis. Dots left of Today are overdue; the further right, the more runway. Cases that share a deadline window stack vertically. 22 of the docket's apps have a known mailing date.
Difficulty is derived from the rejection statutes on the most recent pending office action. §101-driven and multi-statute cases are graded Hard; §112-only and obviousness-type double-patenting cases are graded Easy; everything else is Medium. "Unknown" means we have not yet parsed a statute for that office action.
| Bucket | Cases |
|---|---|
| §101 only | 1 (1%) |
| §101 + other | 4 (6%) |
| §103 only | 24 (35%) |
| §102 only | 3 (4%) |
| Double-patenting + other | 8 (12%) |
| Multi-statute (no §101) | 27 (40%) |
| No statute on record | 1 (1%) |
How the docket's pending cases split across USPTO tech-center bands.
Manual office-action response work runs about 10 hours per case. The time-saved bands below show what IP Author's prosecution pipeline typically delivers — a conservative 20% on the low end, 35% in the middle, 50% on the high end.
